The truss bracket 100 (hereinafter invention) comprises a first side plate 200, a second side plate 210, and one or more web plates 220. The first side plate 200 may be coupled to the second side plate 210 by the one or more web plates 220 such that the first side plate 200 is parallel to the second side plate 210. The invention 100 may join two or more coplanar timber elements 900 at a joint of a roofing truss such that the two or more coplanar timber elements 900 may be retained in a predefined orientation. The predefined orientation may vary based upon the position of the joint on the roofing truss. The invention 100 may be operable to align the two or more coplanar timber elements 900, to limit insertion distance of an individual timber element selected from the two or more coplanar timber elements 900, to establish a pitch of a roof made from the roofing trusses, to hide an end face of one or more of the individual timber elements, or combinations thereof. As a non-limiting example, the roofing truss may be a rigid structure constructed by arranging the two or more coplanar timber elements 900 into an open framework while the two or more coplanar timber elements 900 are lying in a horizontal orientation. The two or more coplanar timber elements 900 may be coupled using embodiments of the invention 100. The roofing truss may then be rotated to a vertical orientation for installation on a building. The roofing truss may be replicated multiple times and used to provide distributed support for the roof. The invention 100 may aid in the rapid construction of a plurality of the roofing trusses where each of the roofing trusses requires joining of the two or more coplanar timber elements 900 in a consistent, reproducible manner.

Throughout this document, reference directions may be stated in terms of the roofing truss being in a vertical orientation as the roofing truss would be when installed on the roof. Front may refer to the side of the roofing truss corresponding to the positions of the first side plates 200 of the brackets and rear may refer to the side of the roofing truss corresponding to the positions of the second side plates 210 of the brackets. Left and right may refer to the viewer's left and right when standing in front of the roofing truss and facing the roofing truss. The top and bottom of the roofing truss are the upper and lower boundaries of the roofing truss as installed, respectively.

The various faces of the individual timber element may be referred as a front face, a rear face, end faces, and side faces. Specifically, the face of the individual timber element that contacts the first side plate 200 may be referred to as the front face of the individual timber element. The face of the individual timber element that contacts the second side plate 210 may be referred to as the rear face of the individual timber element. The smallest faces of the individual timber element may be referred to as the end faces of the individual timber element. The two remaining faces of the individual timber element that are not the front face, the rear face, or the end faces may be referred to as the side faces of the individual timber element.

The first side plate 200 may be a rigid plate that couples to the front faces of the two or more coplanar timber elements 900. The second side plate 210 may be a rigid plate that couples to the rear faces of the two or more coplanar timber elements 900. In some embodiments, the first side plate 200 and the second side plate 210 may be identical in size and shape. In some embodiments, the invention 100 may be operable to retain at least two of the two or more coplanar timer elements 900 to form an oblique angle between the at least two of the two or more coplanar timber elements 900.

The first side plate 200 may comprise a first plurality of fastener apertures 202. The second side plate 210 may comprise a second plurality of fastener apertures 212. The first side plate 200 and the second side plate 210 may couple to the two or more coplanar timber elements 900 using a plurality of fasteners 940 that pass through the first plurality of fastener apertures 202 and the second plurality of fastener apertures 212, respectively. As non-limiting examples, the plurality of fasteners 940 may comprise bolts, nuts, lock washers, flat washers, screws, nails, or combinations thereof.

In some embodiments, a one-to-one correspondence may exist between the positions of the first plurality of fastener apertures 202 on the first side plate 200 and the positions of the second plurality of fastener apertures 212 on the second side plate 210 such that a path may exist for an individual fastener to pass through one of the first plurality of fastener apertures 202, through one of the two or more coplanar timber elements 900, and through one of the second plurality of fastener apertures 212. As a non-limiting example, the one-to-one correspondence may exist between the first plurality of fastener apertures 202 and the second plurality of fastener apertures 212 such that an individual bolt may pass through one of the first plurality of fastener apertures 202, through one of the two or more coplanar timber elements 900, and through one of the second plurality of fastener apertures 212. An individual nut may then couple to the individual bolt to retain the individual bolt.

The one or more web plates 220 may couple to both the first side plate 200 and the second side plate 210 such that the one or more web plates 220 may establish a spacing between the first side plate 200 and the second side plate 210. An individual web plate selected from the one or more web plates 220 may be a rigid plate that couples to the first side plate 200 and the second side plate 210 along opposing edges of the individual web plate. As a non-limiting example, the individual web plate may be welded to the first side plate 200 and to the second side plate 210. Each of the one or more web plates 220 may be perpendicular to the first side plate 200 and to the second side plate 210.

The one or more web plates 220 may be contained entirely between a first boundary plane 214 defined to be coplanar with the front of the first side plate 200 and a second boundary plane 216 defined to be coplanar with the rear of the second side plate 210. The two or more coplanar timber elements 900 that are joined using the invention 100 may be contained entirely between the first boundary plane 214 and the second boundary plane 216.

In some embodiments, one or more of the individual web plates may be bent into a non-planar shape such that the bent web plate may contact more than one of the coplanar timber elements that are joined by the invention 100.

In some embodiments, the invention 100 may be operable to couple the joint of the roofing truss when the invention 100 is populated with less than a full complement of timber elements. As used herein, ‘the full complement of timber elements’ may refer to the maximum number of timber elements that an embodiment of the invention 100 was designed to join together at a single joint. As a non-limiting example, a center bracket 260 at the bottom center of the roofing truss shown in FIG. 1 may be designed to join five timber elements—two horizontally, one vertically, and two at oblique angles to the others. However, in some construction projects it may be possible to safely construct the truss without the vertical timber element or without the two obliquely angled timber elements, thus saving cost without requiring additional bracket part numbers to be available.

In some embodiments, the invention 100 may be used as a pair of brackets with one bracket of the pair rotated by 180 degrees around a vertical axis. As a non-limiting example, the bracket used at heels 930 on the left side of the roofing truss and on the right side of the roofing truss in FIG. 1 may be identical with the bracket on the right rotated by 180 degrees. When a bracket is rotated by 180 degrees, the terminology of the front, rear, left, and right may change to reflect the new orientation of the bracket with the former front becoming the new rear, the former rear becoming the new front, the former left becoming the new right, and the former right becoming the new left.

The orientation of the individual timber element that is retained by the invention 100 may be determined by the location and orientation of the one or more web plates 220, by the location and orientation of other timber elements that are retained by the invention 100, by the placement of the first plurality of fastener apertures 202 and the second plurality of fastener apertures 212, or by combinations thereof. The invention 100 may align the two or more coplanar timber elements 900 by virtue of the fact that the two or more coplanar timber elements 900 may be held in place by the plurality of fasteners 940 that pass through the first plurality of fastener apertures 202 and the second plurality of fastener apertures 212 and by virtue of the fact that one or more of the two or more coplanar timber elements 900 may be adjacent to and aligned by the one or more web plates 220. The invention 100 may limit insertion distance of a first timber element 901 into the joint by virtue of the fact that one of the individual web plates or a second timber element 902 may interfere with the insertion of the first timber element 901 into the joint. The invention 100 may establish the pitch of a roof made from the roofing truss by virtue of the fact that at least one of the two or more coplanar timber elements 900 comprising the roofing truss may be oriented at an oblique angle relative to horizontal. The invention 100 may hide the end of the individual timber elements by virtue of the fact that the end of the individual timber elements may be obscured by the first side plate 200 and the second side plate 210, the individual web plates, another timber element, or combinations thereof.

The following may be non-limiting examples of embodiments of the invention 100 to illustrate various predefined orientations of the two or more coplanar timber elements 900.

In some embodiments, the invention 100 may retain a first timber element 901, a second timber element 902, and a third timber element 903 to form a corner bracket 250.

The center bracket 260 may retain the fourth timber element 904 at a first oblique angle 290 relative to the first timber element 901 and radiating from the junction of the first timber element 901, the second timber element 902, and the third timber element 903. The center bracket 260 may retain the fourth timber element 904 at a second oblique angle 292 relative to the second timber element 902 and radiating from the junction of the first timber element 901, the second timber element 902, and the third timber element 903. The fourth timber element 904 and the fifth timber element 905 may radiate upward from the junction of the first timber element 901, the second timber element 902, and the third timber element 903 in opposite lateral directions. The first oblique angle 290 and the second oblique angle 292 may be congruent angles. In some embodiments, the first timber element 901 and second timber element 902 may be replaced by a single timber element that passes through the bottom of the center bracket 260 and extends in both lateral directions from the center bracket 260.

In some embodiments, the invention 100 may retain a first timber element 901, a second timber element 902, and a third timber element 903 to form a top bracket 270. The top bracket 270 may be used at the top center of the roofing truss where top chords 920 meet with a king post 924. The first timber element 901 may be the king post 924.
